State of Massachusetts, have invented an Im rovement in Corrugated Sheets, of

- which the following description, in connection with the accompanying drawings, is a specification, like letters on representing like parts.

This invention is an improvement-in corrugated composite sheets which may be used in making boxes and for other closures or purposes.

The character of the invention may be best understood by reference to the following description of an --illustrat-ive embodiment thereof shown in the accompanying drawing, wherein:

Figure 1 is a plan view of a portion of a composite sheet embodying the invention, parts being broken away; Fig. 2 is a side elevation of the sheet shown in Fig. 1; and Fig. 3 is a perspective view of a box made of a composite sheet embodying the invention.

I will first describe the composite sheet and then a use thereof as typified by the box shown in Fig. 3.

the drawings Referring to Figs. 1 and 2, 1 designatesa layer of corrugated paper or other mate-.

rial constituting the body of the sheet; 3, 3 designate wear-resisting layers on opposite sides of said corrugated layer of textile or reticulated fabric or other suitable material, preferably woven, the material shown herein being conveniently of commercial burlap.

-5, 5 designate intermediate fiat or sheetlike layers of paper or other suitable material interposed between the corrugated layer 1 and the textile layers 3, 3. These intermediate layers are suitably secured 'to the opposite faces of the corrugated layer as by an adhesive. The intermediate layers may be of waterproof material or on their faces contiguousto the textile layers there may be supplied a waterproof coating of asphalt, or other suitable waterproof material which, if desired,- may constitute the adhesive for securing the textile layers to said intermediate layers.

In making a composite sheet such as described, the textile fabric will be pressed or embedded more or less into the adhesive or waterproof coating of the flat paper sheets and, as a result, the threads of the fabric Specification of Letters Patent.

will be individually, securely held to the said paper layers.

A sheet composed of'layers such as de-' scribed, presents a very advantageous construction. The corrugated layer contributes st1finess to the sheet which is supplemented by the flat paper layers conjoined to theopposite faces thereof, said layers constitut-' mg effective binders for securing the burlap to the corrugated aper. The textile layers which const1tute t e exterior faces of the sheet add to the strength of the latter and present effective wear-resisting surfaces. The inherent flexibility of the asphalt waterproof material and the flexibility of'theifabr1c prevent cracking'of the waterproof material. The fibers or threads of the fabric preferably project abovethe face of the waterproof material and present a clean, non-adhesive fabric surface protecting the waterproof material and preventin any possibility of the latter being scrape from the paper layer. If the corrugated paper la er becomes wet the corrugations thereof Wlll tend to flatten and'become ineffective as stiffening members. One great advantage is to effectively protect these corrugations from moisture.

While the sheet shown herein includes textile layers on opposite sides of the sheet it will be understood for many purposes it will sufiice to have a fabric layer on but one and preferably the exterior side of the sheet.

Having described the sheet material, I will now describe a use thereof with more particular reference to Fig. 3 wherein is shown a box or carton comprlsing sides 7 and ends 9 formed of one continuous strip preferably having the corrugations of the sheet extending vertically, thereby permitting the sheet to be more readily scored and bent to form the corners of the box. The composite sheet adapts itself readily to the formation of a tight union at the juncture of the ends of the sheet as well shown in Fig. 3 wherein the outside paper and textile layers are together extended beyond the corrugated. layer to provide a margin 11 overlapping the end of the box,'said margin being secured thereto" by an adhesive, or otherwise, as desired. By this construction it is not necessary to use an additional strip of cement tape or other material to secure the meeting edges together, but the latter are securely retained by portions of the-main body of the sheet of which rial No. 649,806.

4 the box is formed. The cover and bottom of the box may be formed of opposedend and side flaps 13, 15, folded over and, if desired; of an extent to meet one another. The

overlapping end and side flaps constituting the cover and bottom of the box may be secured together by an adhesive.

A box formed of the composlte waterproof sheet material described presents a number Having described preferred embodiments A of the invention without limiting myself thereto, What I claim as new and desire to' secure by Letters Patent, is:

1. A composite sheet comprising a layer of corrugated. stiffening material, a sheetlike waterproof layer secured to the ridges of the corrugations, and a wear-resisting layer of textile fabric applied to said waterproof layer for protecting the same.

2. A composite sheet comprising a layer of corrugated stiffening material, a sheet- 'like waterproof layer secured to the ridges of the corrugations, and a wear-resisting fabric layer in adhesive 1 engagement with said waterproof layer for protecting the same. 1 4

A 3. A composite sheet comprising a layer of corrugated stiffening material, a sheetlike Waterproof layer secured to the ridges of the corrugations, and a reticulated fabric layer applied to said waterproof layer for protecting the same.

4. A composite sheet comprisinga layer of corrugated stiffening material, a sheetlike waterproof layer secured to the ridges ofl'the corrugations, and a fabric layer applied to said waterproof layer and presentmg a fabric wear-resisting surface.

5. A' composite sheet comprising a layer of corrugated stiffening material, a sheetlike waterproof layer secured to the ridges of the corrugations, and a protective fabric layer having fibres thereof somewhat embeddedin the waterproof material of said waterproof layer.

6. A composite sheet comprising a layer of corrugated stiffening material, a sheetlike layer secured to the ridges of the corrurgations and having a waterproof coating of asphalt, and a burlap layer applied to said waterproof coating for protecting the same.

7-. A composite sheet comprising a layer of corrugated stifi'ening material, a sheetlike waterproof layer secured to ridges on resisting fabric applie to said waterproof layer for protecting the same, and a layer of textile fabric for protecting the opposite side of said corrugated layer.

8. A composite sheet comprising a layer of corrugated stifi'ening material, a sheetlike waterproof layer secured to the ridges at one side of said corrugated layer, a wearresisting fabric layer applied to said waterproof layer for protecting the same, and a sheet-like layer secured to the ridges at the opposite side of said corrugated layer.

9. A composite sheet comprising. a layer of corrugated stiffening material, sheet-like waterproof layers secured to the ridges at the opposite sides of said corrugated layer, and wear-resisting fabric layers applied to said waterproof layers for protecting the same. 1
